WASHINGTON (AP) — The Washington Nationals finally ran out of patience waiting for Trevor Rosenthal to throw strikes following his return from Tommy John surgery.

Rosenthal was released by the Nationals on Sunday, less than 24 hours after the 29-year-old reliever walked all three batters he faced in a 13-9 loss to Atlanta.

After undergoing elbow ligament replacement surgery in 2017, Rosenthal sat out last season before signing as a free agent with Washington in November. The Nationals were hopeful he would pitch as he did in 2014 and 2015 with St. Louis, when he totaled 93 saves.
